Powers:Mikhail's powers have always been rather ambiguous and have never fully been explained. The Age of Apocalypse version is said to, "command energy and force forces." In various appearances he is shown to be able to manipulate the substance of matter on a subatomic level and warp energy wavelengths, allowing him to fire destructive blasts and teleport through space and dimensions although the full extent and limit of his powers are unknown.

Bio:The older brother of Colossus, Mikhail was a Russian Cosmonaut and was believed dead after a faulty mission where his space shuttle exploded. However, it was later discovered that the explosion was set up by the government who learned of Mikhail's powers and wanted to exploit them without the family's interaction.

Mikhail was sent by his superiors into an inter-dimensional void, counting on his powers to keep him and his comrades safe, to see what was on the other side. He found a world, although he was the only survivor of his crew. He soon became a messiah-like figure and found himself embroiled in a civil war. The X-Men happened to end up on the same planet, and told Mikhail that he had to close the void before it destroyed both this world and their home. However, having had one failed attempt that killed many, Mikhail was apprehensive to try it again. With the help of Sunfire, Iceman, and Jean Grey he succeeded, and was transported home where next he appeared with the Morlocks.

Tragically, after Mikhail set himself up as leader of the Morlocks, the tunnel-dwelling mutants beneath New York City, he massacred nearly all of them by flooding the tunnels. He did, however, survive, along with Callisto the former leader of the band of outcasts and a group of Morlocks who later descended to form Gene Nation. In a world where time moves faster than normal, Mikhail had established a citadel for himself on the top of a massive hill. The pseudo-Darwinian philosophy of "survival of the fittest" was the only thing which governed the society. If someone could reach the summit of the hill they were considered "fit" and worthy of being part of Gene Nation. Mikhail was forced to transport Storm and the Gene Nationals back to Earth, but he escaped once more (presumably back to the Hill) ranting about his benefactor being displeased with him. Storm then transported all of the Gene Nationals to a dying village in Africa where they would eke out a new life for themselves. It was discovered that Mikhail was working for the Dark Beast to try and propagate a group of elite warriors.
Distraught by the death of his little sister Illyana by the Legacy Virus, Mikhail decided to do something. Mikhail goes back and exposes his sister to the virus when she is in her aged form, thinking that with her magical abilities it would shield her from harm and help her to build an immunity. It was later revealed that Mikhail himself was suffering from the disease and was also trying to rid his body of the fatal virus. However, his plan backfired and Illyana contracted the disease, her brother having been the one to administer it to her.

When Xavier temporarily disbanded the X-Men for reasons of his own, Piotr took Marrow with him to Boston, in order to check out an art expo. While there, they were shanghaied to the Hill by Mikhail Rasputin, and Colossus came face-to-face with his brother for the first time since his supposed suicide. The pair of X-Men ended up freeing Mikhail from the corrupting influence of a sentient energy native to that dimension and brought him back to the mansion to recuperate when the entire team became embroiled in the gathering of the Twelve. Mikhail was one of these legendary Twelve, and one of the Horsemen breached the mansion's security to kidnap him. Colossus joined a strike force of X-Men who traveled to Egypt in order to confront Apocalypse, and his Skrull allies. In the resulting battles, Mikhail sacrificed himself to carry the Horsemen away from the conflict in a dimensional gateway. Although some Horsemen have reappeared since then, Mikhail did not.

Mikhail has made his reappearance and this time had allied himself with Sinister. The two were attempting to assassinate all of the members of the Rasputin family but one, so that the spirit of their forefather Grigory Rasputin may be concentrated and reincarnated in the last remaining member of the lineage. Mikhail teleported himself and his brother to another dimension that was a series of rocky caves. Not wanting to physically kill his brother, he decided to leave him in the rock dimension where he would die in a matter of weeks. However, away from Sinister for a period of time, he was able to overcome his mental manipulations and came to his senses, rescuing his brother. His final decision was to teleport to a world named The Dark Zone, a dimension from which it was impossible to return and also once entered, impossible to die in. This protected the rest of the Rasputin line from the depredations of Sinister as at some point Mikhail would have been the sole surviving Rasputin, which would then trap his ancestor in the dark zone. Colossus tried to persuade him to save himself, but Mikhail determined that it would be best for the possible problem and for his own insanity.
